Looking good! Have you tested the runtime migration with an upgrade in zombienet?
I've always discovered bugs by doing that in the past 😆

Not yet, but I don't really expect any issues, it is a very simple migration.

+) -> BTreeMap<ParaId, BTreeMap<u8, BTreeSet<CoreIndex>>> {


Some type alias should help here.

Agree :)
Also, I find it a bit strange to have a BTreeMap<u8, BTreeSet<_>>
instead of a Vec<BTreeSet<CoreIndex>> where the index in the Vec represents the depth. Given that the depth is supposed to be a number 0..x and without gaps IIUC

Nice work!

Looking good overall!
Left some questions for my understanding and potential corner-cases

+			let core_index =
+				**assigned_cores.get(core_selector.0 as usize % assigned_cores.len())?;


what i didn't get from the RFC is why do we need to do % assigned_cores and not assume that the core_selector < assigned_cores.len()?

+		{
+			let (upward_messages, ump_signals) = upward_messages.split_at(separator_index);
+
+			if ump_signals.len() > 2 {


is 0 ump_signals allowed in case there's a separator?
is multiple separators allowed? we only look here for the last one
my thinking it should be no in both cases - might be good to validate those

+	buffer: VecDeque<RelayParentInfo<Hash>>,


since we're making breaking changes to a storage that is used by a runtime API, we should make sure to workaround the recently experienced issue: #5738 by adjusting it

polkadot-sdk/polkadot/runtime/parachains/src/runtime_api_impl/v10.rs

Line 454 in d31bb8a

let min_relay_parent_number = shared::AllowedRelayParents::<T>::get()

🤦🏼‍♂️ good catch, I missed this, was thinking it is only used internally and not exposed via API.
